Description
Technical field
The present invention relates to a kind of emulsifying agent, particularly a kind of environment-friendly type diesel oil emulsifier.
Background technology
Energy and environment are two big problems that human society faces, and existence has great importance to human society for energy shortage, environmental pollution, and the obnoxious flavour that discharges after the oil inflame is an important factor of environmental pollution.Therefore, how to solve energy shortage, problem of environmental pollution with regard to the problem that become current social science circle and pay close attention to most, save energy, reduce environmental pollution and caused human great attention.
Propose water is mixed this imagination of improvement burning in the oil fuel as far back as the just just existing people of eighties of last century; The U.S., the FSU and some industrial countries of Europe; The applied research of beginning emulsification water blending fuel oil is because under condition at that time, the emulsified fuel state of the art is lower; Energy problem is not outstanding, and the Emulsified Fuel Technology at Power development is in low state more slowly.
Later stage nineteen fifties; Environment and development contradiction is day by day obvious, and oil crisis begins to occur, and the oil fuel technology for mixing water that possesses the dual function of energy-saving and pollution-reducing obtains to pay attention to; The U.S., the FSU, Japan etc. all classify this technology as national main project and develop research; And obtaining positive application achievements, in first annual meeting of the world of holding in July, 1981 burning association, the Emulsification of Fuel Oil emulsifying combustion is classified as one of three big conservation measuress.China also carries out active research in this field, and obtains certain achievement from the fifties end.Early eighties, in view of China's energy shortage, State Planning Commission, State Scientific and Technological Commission, the Chinese Academy of Sciences dispatch a joint document, fabric study's Emulsified Fuel Technology at Power, the numerous and confused input of national correlative study mechanism and individual studied, and obtained certain practical achievement.
Water is polar compound as everybody knows, and petroleum products is by the non-polar compound hydrocarbon composition, and water and oil are immiscible; Make the two become the mixed solution that dissolves each other, need wherein a kind of liquid to be dispersed in the another kind of liquid by external force or adding tensio-active agent; Become metastable mixed solution; In fine chemistry, this mixed solution is referred to as emulsion, and the emulsion of being made up of oil fuel (kerosene, gasoline, diesel oil, heavy oil, residual oil) and water just is called as emulsion fuel.The diesel oil emulsification technology is by the certain process proportioning with diesel oil, water and emulsifying agent; In mechanical means through certain technological process of production; Form a kind of " water-in-oil " type diesel oil emulsification through Over emulsfication, comprising the development of emulsification mechanical means and the synthetic and screening of emulsifying additive.
Emulsified fuel oil is the same with common emulsion, also is divided into water-in-oil-type (W/O) and oil-in-water-type (O/W), in water-in-oil type emulsion fuel oil; Water is to be suspended in the oil equably with disperse phase; Be called as disperse phase or interior phase, oil fuel then wraps in the skin of the globule, becomes external phase or foreign minister.Our present being seen most of emulsified fuel oils all are water-in-oil type emulsified fuels.Oil-in-water type emulsion oil fuel is just in time opposite with water-in-oil-type.
Emulsified fuel oil belongs to thermodynamic unstable system, and under the effect of external force field (gravity etc.), emulsified fuel oil is layering gradually; Its minute, interval velocity became quadratic relationship with the radius of drop; Not only do not play the energy-saving and pollution-reducing effect after the emulsified fuel oil generation layering, serious meeting causes burning to interrupt, and this must select suitable emulsifying device; With being distributed to suitable particle diameter in the emulsified fuel oil mutually, so that emulsified fuel oil reaches the relatively stable period of request for utilization.
The unsettled major cause of emulsified fuel oil system is that water oil is immiscible, and their surface tension are separately formed the IT of intersection, and IT is shunk the water-oil interface liquid phase gradually, causes agglomeration separation separately at last.Emulsifying agent is a tensio-active agent, and it mainly acts on is to reduce IT.
Tensio-active agent generally all is made up of polar group and nonpolar group two portions on chemical structure, polar group possess hydrophilic property matter soluble in water; So be called hydrophilic group, nonpolar group is soluble in oil, so be called oleophilic group; After in oil-water system, adding emulsifying agent, hydrophilic group is soluble in water, and oleophilic group is dissolved in the oil; So just between oil-water two phases, form the fine and close interfacial film of one deck, reduced IT, simultaneously drop is shielded.On the other hand, because absorption and effect such as friction make liquid droplet charged, charged drop forms double electrical layers in the both sides at interface, because the repulsive interaction of electrostatic double layer makes drop be difficult to gathering, thereby has improved the stability of emulsified fuel oil.
Kinds of surfactants is very many, but generally by following formal classification:
(1) by the solvability branch: water-soluble and oil soluble.
(2) by the decomposable ions branch in water: ionic and non-ionic type.
(3) by the ionic branch in water: anionic, cationic and amphoteric ion type.
At present more in the emulsifier for fuel oil is to adopt the tensio-active agent of several kinds of different activities such as anionic, cationic, non-ionics to carry out composite use, to reach comparatively ideal stabilising effect.
When different oil products were prepared oil in water emulsion, their used emulsifying agent hydrophile-lipophile balance values (HLB value) were inequality, and this all must and go concrete allotment through a series of tests in actual use.Present diesel oil emulsifier on the market is large in the variety; But great majority are in order to consider cost and emulsifying effectiveness; Sodium alkyl benzene sulfonate (ABS) and TX10 (APEO) have been adopted in the prescription in a large number; Though the emulsifying agent emulsifying effectiveness of these structures is good, biological degradation is bad or harmful to water body, belongs to environment harmful.
Summary of the invention
